The front PDC has 4 parking sensors fitted on the front bumper which requires 6 wires from PDC ECU to the front. So basically the retrofit is about how to connect the front PDC sensors and PDC ECU via 6 wires.
I have successfully done this on my F54, I believe F56/F55/F57 should be the same.
You can find how to retrofit the rear PDC at below link if your car has no PDC at all.

1, wiring

PDC ECU pin out

Below red boxes showing the pins that are needed for front PDC retrofit, 4 signal wires for 4 PDC sensors and all 4 sensors are using the same power and ground wire. So total 6 wires needed.

I would suggest running 8 wires rather than just 6. Pin2 and Pin13 are for PMA, better run the additional wires at same and retrofit it later. Also you could just leave them there if you don’t need them.

Don’t need them if you bought the crimps with wire from BMW/Mini​

Wires​
8​
8 meters each wire, you only need a total 6 for PDC. Again I did 2 additional wires. You can choose your own colour, or you can use the same colour wire with labels.​
0.35 wires, I used 23AWG​

Bumper trims:
I didn't buy the front bumper trim, I drilled holes on my own bumper. The PDC brackets are not for sale individually.
I bought a damaged whole front bumper with those brackets, I removed those brackets and used them on my car. Just for reference the outer holes are 51mm and centre holes are 31mm. But they are not standard holes, they are slope holes. I end up using a knife to make 4 slope holes after drill standard holes ( believe me, not fun at all).

Crimps:
For the crimps, again I didn't buy the BMW/Mini crimps. I made my own crimps so that I don't have to solder them.

Sennsors:
Parking sensor, you can use BMW/Mini sensors, also there are many others brands you can use.
Valeo makes the same sensors, puts different logos and ships to different car manufacturers.


From the above link, you can easily find the actual Valeo sensors' part number or the other car that used the same sensor.
For example,
BMW:66209274427
Valeo P/N:890019
Audi/VW/Skoda/SEAT/PORSCHE : 5Q0919275/5Q0 919 275 B /5Q0919275B /5Q0919275BGRU
MERCEDES-BENZ: 0009055504/0009059300/A0009055504
TOYOTA: 89341-F4010-C0/89341-F4020-A0/89341-F4020-A1/89341-F4020-B0.......
VOLVO: 31381691/31400992/31471005
LAND ROVER: LR059784

** Check your sensors as soon as you receive them. Use a multimeter, check the resistance between pin1 and pin3 on your sensor. The reading needs between 1.5-1.8M ohms. Don't ask, I learnt the hard way ( I removed my front bumper twice to find out that I have 2 faulty 6620927447 sensors).

Wires

Regarding wires, my car is UK spec and I end up to run wires via the left side firewall which is why it needs 8 meters for each wire. I also used car fabric harness tape to protect the wires that I made.

All my parts are from ebay or Aliexpress.

3, wiring from PDC ECU to X252 connector.

My car is F54 UK spec, I check the firewall and can’t find any spare grommet on the right side of the car to let my 8 wires go through. So I decided to run wires from PDC ECU to the left side of the car to cross the firewall as I can easily find 2 unused grommets.
IMG_20210322_235111.jpg
Below the red line is my wiring route.
wiring F54.JPG
To do the wiring, you need to remove the boot trim on both sides, left door trims and glove box.

*DO NOT fit crimps on wires before going through the firewall.


Here are some photos during my retrofit.
Insert crimps to the PDC ECU and then start making my own wire loom.
IMG_20210327_180107.jpg
There is lots of space under the boot door trims.
IMG_20210418_091803.jpg
I attached the new wires to the existing wires route on the left side.

I didn’t use any cable tie inside the car, I used car fabric harness tape to tape my wires to existing wires to avoid any noise. For sure I used cable ties in the engine bay to secure my wires.

The X252 connector should reach to the back of your windscreen wash bottle. Here is the photo:

You’ll have better understanding from below video:

4, Front PDC install

First, remove the front bumper, there are lots of guides already. The most difficult part is to remove the front wheel arch trim.

Here is my tips:
1), only remove the front 3 clips.
73520


2), all above 3 clips can be pushed out from inside. I used a small socket which was just about the same size of the clip.
Below photo is the first one. You can’t see the third one, you can reach it easily. The middle one can be pulled out or you can release the wheel arch and push it from back.

3) there are 4 latches at the front of the trim, on CooperS you can reach 3 out of the 4 latches with a long stick.
s-l1600 (3).png b20617c6923309580e0c8207b0a9f5bd-700.jpg
Using a long stick from the front vent you can easily release the 2 clips in the green circle and the front part of the yellow circle. From the back vent, you can reach the other half latch in the yellow circle. You can reach the red one if you remove the headlight, I used a fine stick to release the latch in the red circle when I have a tiny gap between trims.


Once removed the front bumper, just swap trims if you bought new trims.
There are marks already on non-PDC ready trims, I made holes in mine.

Regarding the wiring, the 6pin connector needs to be attached to the back of the screen wash bottle. You would be better using the bottom fixing point as the PDC wires are just about the right length, really tight fit. You need to make sure to let the connector mating end facing outside, so you can plug your newly made connector to it.

Then you run the loom to the front crash bar, and attach the wire clips to your front bumper (yes, the front bumper). Becareful at this part, the Mini didn’t give much space to attach them to the front bumper.

5, coding

Simply change VO 507 to 508 and apply to PMA, HU and BDC.
Now you should see parking in your setting list and you can choose active/deactivate auto PDC.
IMG_20210427_214245.jpg
The front PDC will show on your HU display when selecting reverse gear.
Your front PDC will automatically activate at low speed if you activate the auto PDC(I believe is about 8 miles/hour), but it only gives you beeps and changes screen to PDC screen when you are about 0.5m or less to an objective at front.

You can also manually active/deactivate the PDC function if you have the parking switch fitted.

Hope this can help others who want to have a front PDC on their car.
